Abstract (en)
[origin: EP1120343A2] A spacecraft (90; 26) protected by a coating (20) includes a spacecraft (90) such as a communication satellite has an external surface (25) and a coating (20) of the external surface (25) of the spacecraft (90). The coating (20) is formed of a binder (24), and a plurality of pyroelectric/ferroelectric pigment particles (22a), preferably ferroelectric particles, bound together by the binder (24). Each ferroelectric pigment particle (22a) includes a ferroelectric pigment material having a ferroelectric/paraelectric transition. The coating (20) may also include active secondary particles (22b) and/or inert particles (22c). The coating (20) may operate in a passive mode or an active mode with the application of a bias voltage (100) to the coating (20) (Fig. 1). <IMAGE>
